Digital signal levels:
(*) Digital output low is 0V (<0.5V), output high is either 12V or 24V (+/-1V), depending on pin 8.
(**) Digital input low is 0.5V or lower, input high is 8V or higher.

Digital Interface
The connector labeled DIGITAL INTERFACE is an RJ-45 connector that can be either an Ethernet port or an RS-485
half-duplex (2-wire) serial port with industry standard pin-out (pin 4 = RS485-B, pin 5 = RS485-A, pin 7 = 24Vdc, pin 8
= GND, the rest are not used).
The protocol to communicate with the units is MODBUS-TCP with the Ethernet port, or MODBUS-RTU with the serial
port. MODBUS-RTU over Ethernet is also available with the Ethernet port.
If the unit is enabled via the digital interface, it will respond only to the digital interface setpoints and not to the analog
port.
